taking photos

I'm going to be travelling around 4-5 and plan to take my brother's digital camera. I'm one of those people who will take a photo every minute, so I'll need to transfer my photos to a memory stick or my iPod so I can continue taking more photos. I'm just worried about this. If I lose my memory cards/sticks I'll lose all the photos or if I damage or lose my ipod (hope not), I'll lose my photos.

Any suggestions? Burning onto a CD at internet cafe? Uploading them to your email account (will this take too long?) Getting them developed as I go and posting them home?
